Web development is the coding or programming that enables website functionality, per the owner's requirements. It mainly deals with the non-design aspect of building websites, which includes coding and writing markup.
Web development ranges from creating plain text pages to complex web-based applications, social network applications and electronic business applications.
The web development hierarchy is as follows:
Client-side coding.
Server-side coding.
Database technology.
i use Hypertext Markup Language (HTML), Cascading Style Sheets (CSS), and JavaScript to develop websites.
HTML defines the basic framework of a website – the foundation upon which everything else is built upon. It forms the blocks that define a page’s layout, format, and critical components. Although it is theoretically possible to code a website on HTML only, it will be just a barebone site with no functions unless it’s enriched with CSS and JavaScript. Also, even simple style modifications such as changing the color of a button require a lot of coding to be executed using HTML only.
CSS is used to style the content of a website using a small set of files that are kept across the entire site. This way, whenever a change must be applied to say, consistently change the color of all the buttons found in every page of the website, a web dev needs to edit only a single file in CSS.
The JavaScript programming language is used to take care of the interactivity of many unique website elements. It can be used to create effects that alter the appearance of icons and drop-down menus, add animations, games, and other interactive elements.
